HORIZONTAL COKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 615,709, dated December 13, 1898.

Application iiled March 30, 1896 T all whom, t may concern.:

Be it known that we, ALBERT HSSENER, residing at Essen-on-the-Ruhr, and LOUIS HOL- BEoK and JOSEPH KIEsoHErNK, residing at Uechendorf, near Gelsenkirchen, Prussia, Germany, subjects of the King of Prussia, German Emperor, have invented new and useful Improvements in Horizontal Coke-Ovens, of which the following is a specification.

The present invention relates to that class of coke-ovens having horizontal flue systems in which the gases generated in the cokingchambers are burned with the air fed to the system.

The invention consists, essentially, in the peculiar arrangement of the iiues, by means of which each side of each coking-chamber is provided with a separate Hue system, so that one or the other side of either of the said chambers may be more or less intensely heated at the will of the operator and entirely independently of the other chambers.

The nature of our invention will best be understood when described in connection with the accompanying drawings, in which-A Figures 1 and 2 are Vertical sections through the iiues and through the coking-chambers, respectively. Fig. 3 is a broken vertical section of Figs. 1 and 2, the part between lines 1 1 and 2 2 being taken on lines 6 6 of Figs. 1 and 2, the part between lines 2 2 and 3 3 on lines 7 7, the part between lines 3 3 and 4 4 on lines S 8, and the part between lines 4 4 and 5 5 showing an end view from the right side of Figs. 1 and 2. Fig. 4 is an end view of one oven seen from the left of Figs. 1 and 2. Fig. 5 is a detail transverse section, drawn on a larger scale, of the partition-walls between the coking chambers, showing `the manner of constructing the lateral flue systems. Fig. 6 is a similar section showing a modified form of construction for the same. Fig. 7 is a similar section showing another modification. Figs. 8 and 9 are vertical sections through the ilues and through the cokingchambers, respectively, of a modified form of oven. Fig. 10 is a broken vertical section of Figs. 8 and 9. Fig. 11 is an end view of one oven seen from the left of Figs. 8 and 9. Fig.

Serial No. 585,341. (No model.)

12 is a horizontal section showing the airheating arrangement of Fig. 8, the section being taken on the line I K, Fig. S. Fig. 13 is a cross-section on the line 13 13, Figs. 8 and 9. Fig. 14 is a cross-section on the line 14 14, Figs. 8 and 9. Fig. 15 is a horizontal section on the line 15 15, Fig. 8. Fig. 1G is a horizontal section on the line 16 16, Figs. S, 9, and 10. Fig. 17 is a similar section on the line 17 17, Figs. 8 and 9.

Similar letters of reference designate corresponding parts throughout the several Views of the drawings.

According to the present invention and in contradistinction to the systems hitherto employed two lues a and b are formed beneath the sole of the coking-oven D, said iiues being entirely separated one from another by means of a partition-wall. Each iue communicates by means of a passage a0 and b with its corresponding uptake of and b5, the upper ends of which open into the horizontal zigzag fine systems a a2 a3 a4 and b b2 b3 b4, respectively. The lowest flues of.4 and b4 of each system communicate by means of a short canal with the waste-flue A for carrying off the waste products of combustion from all the coking-chambers D. The gases from the coking-chambers are conducted into the fiue systems by means of the pipes i or la in the well-known manner, air being allowed to enter the iiues in suitable quantities by any well-known means, such as jet-openings, as shown.

From the above description it will be evident that each side of each coking-chamber will be heated by a separate fine system and that each flue system may be regulated quite independently at the will of the operator, so that one or the other side of any one flue may be more or less intensely heated, according to requirement.

We are aware that subsole-ilues have been employed prior to the present invention, but

- no arrangement has hitherto been devised, as

farl as our knowledge goes, of a duplicate subsole-iiue system having each member communicating separately with one laterally-aw ranged flue system.

As shown in Figs. 5 to 7, the partition-walls between the ticking-chambers are constructed to receive the whole weight of the chamberroof, the slabs d d and the horizontal slabs c c, forming the lateral flue systems, being dovetailed together, as shown in Fig. 5 and in two modified forms in Figs. 6 and 7. All strain due to the weight of the roof or vault of the chamber is thus taken oft the thin slabs d d, which may consequently be very light. The arrangement shown enables the slabs d CZ to be easily and conveniently taken out and exchanged without interfering with the bond of the masonry of the partition-walls.

The oven above described is intended for working with ordinary cold-air feed; but in Figs 8 to 12 we have illustrated a construction of the oven showing auxiliary lues for previously heating the air fed to the lne systems. In this case the lowest arm of each horizontal iiue system a4 b4 is arranged at a lower level, lying underneath the level of the subsole-iues a and b, and between the said i'luearms a4 and b4 are formed auxiliary fines e and f, through which the cold air is conducted prior to its being fed to the lateral iiue systems for combustion. As shown in Fig. l2, the air-channels c and fextend from one side of the oven to the other and supply hot air to main pipes g and t on opposite sides of the ovens, from which main pipes it is supplied to the heating-fines by the pipe systems m. The pipes or fines e and f alternate, the pipe c taking the cold air from one side of the oven and supplying it as hot air to the pipe system m at the opposite side and the pipe f taking cold air from the opposite side and supplying it as hot air to the side of the oven at which the pipe c takes its cold air.

l. In a horizontal coke-oven for recovering the by-products, the combination with the partition-walls between the coking-chambers and a separate system of zigzag iiues at either side of each of said chambers, of a separate and independent subsole-tlue for each of said flue systems, whereby the flue system on one side ot' said chambers is heated and controlled independently of the system on the opposite side, substantially as and for the purpose described.

2. In a horizontal coke-oven for the recovery of the by-products, the combination with the partition-walls between the ceiling-chambers and a separate system of horizontal zigzag fines at either side of each of said chambers, of a separate and independent subsole-flue for each of said flue systems, whereby the flue system on one side of said chambers is heated and controlled independently of the system on the other side thereof, and a series of auxiliary air-channels passing through the said coke-oven, and each having one end open for the reception of the cold air, and a pipe system communicating with the other end for feeding the air to the flue system, substantially as described.

3. In horizontal coke-ovens for recovering by-prodncts having partition-walls between the coking-chambers and a separate system of zigzag Iiues at either side of each of the said chambers, the combination of a duplex subsole-iiue having each of its members separately and independently communicating with one of the said lateral line systems, each of these members being connected to one uptake of each side-wall flue system and of a series of auxiliary air-channels lying between the lowest Waste-heat lues in the lowest part of the foundation of the oven, extending with both ends through the front walls of the ovensmone end of these channels leading to the open air for the reception of cold air and the other end communicating with the pipes for leading the heated air to the gaswsupplyentering the heating-dues for the purpose of combustion therewith, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
